Core Concepts
Integrating foundation models with clustering improves cold-start active learning.
Abstract
Active learning selects informative samples within a limited annotation budget.
Previous studies lack focus on selecting samples for cold-start model initialization.
Foundation models generate low-dimensional embeddings for clustering.
Experiments on clinical tasks show enhanced performance with foundation model-based clustering.
Proposed method offers an effective paradigm for future cold-start active learning.
Stats
Random sampling prone to fluctuation.
Naive clustering faces convergence challenges with high-dimensional data.
Foundation models generate informative embeddings for clustering.
